NETWORKS! By: - A network is a system allowing computers to communicate with each other.- It links microcomputers together allowing them to share resources.- They are also called centralized systems as data flows to and from computers linked to a network.- Networks can connect to PCs, Macintosh computers, IPods, and more. What is a Network? Types of Networks LAN Local area networkConnects in small area Can also be classified based on type of architecture:Peer to peer – each computer has equivalent capabilitiesClient/server:Client – users run applications relying on servers for resourcesServers: processors managing drives, and providing resources Different types of Network Wide area networkConnect over long distancesLANs connected together WAN MAN Metropolitan Area NetworkData network for a town or city CAN Campus Area NetworkConnect computers in limited areaLANs connected togetherEx. school HAN Home area networkConnects digital devices in home environment Advantages and Disadvantages Bibliography "Network."

The ebook was also used. Review Questions 1. Explain what a network is.A network is a system allowing computers to be linked together so they can communicate and share resources and files.2. Networks can be called centralized systems as all data flows to and from these computers. True3. Identify each of the networks types shown in the following:MAN: Metropolitan Area NetworkWAN: Wide Area NetworkHAN: Home Area NetworkLAN: Local Area NetworkCAN: Campus Area Network4. Which part of the network holds the data and which holds the application software?a) Server: stores the datab) PC: holds the application software Review Questions 5) List 3 feature or benefits of being on a Network:larger storage capacity for data and programsability to backup data on a networkshare resources with other computers on a network6) In order to be connected to a network, the computer system must have which hardware item(s)?d) all of the above (You need a network interface card, cables , router, and modem.)7) To access the network you need to have a user password and login assigned to you.True 8) Everyone who logs onto a network has the same access to all files and programs.False9) The speed at which you can access items depends on what?e) all of the above ( speed of your computer , and how fast it connects to the network, determined by the amount of requests, and the amount of users using that network.)10) When you log onto a network, the computer will run a script that tells the network what access rights you have on the network.True Connecting To Networks The first thing you need is a network interface card. It will need to be installed properly for it to function.You need a connection in the form of either cables or wireless.If you are using a wireless connection you will need a router along with your network interface card. Interacting with Networks This is what you do after you have installed the program, as well as the computer recognizes the program, which it can be opened when commanded.You need a computer ID to access the program. Depending on the requirements your computer will then start running a script, which is also known as a mini program; that will tell the network that it now has access to your computer. SOME EXAMPLES ARE:printers, modems, folders et.cYou can access the programs on the files and file programs on the computer hard drive. Examples of types of file names that might be shown on your computer. CONTINUED .... You will need a access file, which you can easily access the program, when you use this program your are sending a request to the network. The speed of your network computer determines the spreed of your system, or the number of requests made on that network. How the program will run!
